"If a PC is running on 32 Bit good, it does not mean it runs same
on 64 Bit, because all internal drivers are different.
Also it can run for Firewire, but not for PCI with wrong settings.
Mostly, energy save settings of any kind are the problem.
Your audio PC:
For an audio PC (with little ASIO latency) you have to do some adjustments,
because Core i7, i5, i3 PCs can have ASIO clicks even with little CPU usage
and 25ms latency. At least you should
deactivate the following settings
in your PC BIOS :
Intel EIST
Intel C State
C1E Support
Overspeed Protection
Hyperthreading
Execute Bit Support
Set Limit CPUID MaxVal to 3 (maybe not so important)
Intel Virtual Tech
Intel VT-d Tech
In addition the energy save settings of your operating system should be set to maximum.
Our 64 Bit version works perfectly with 4ms, when the PC is set correctly,
with all Scope hardware."
